how to create a psuedo hash in excel
 

I have 4 columns of data
first column is a list of US cities

second columns is the change in population from 1990 to 2000 for the
cities
in the first column

third column is a list of US cities (not all the same cities as the
first or in the same order)

fourth column is the change in average income from 1990 to 2000 for the
cities in the THIRD column.

I want to turn the 3rd and 4th columns into a psuedo hash table so that
I can match the cities in the first column with the third column, and
then store them in cells corresponding in order to the first.

Is it possible to match text this way in excel using functions and not
having to write a VBA script?
